The preparation of novel organic disulfides containing the 2-(substituted phenyl)quinolin-4(1H)-one ring is described. The synthesis starts from thioanthranilic acid esterified with various bromoacetophenones. Cyclization of the resulting phenacyl thioanthranilates in trifluoroacetic acid afforded a mixture of 2-(substituted phenyl)-3-sulfanylquinolin-4(1H)-ones and 3,3′-disulfanediylbis[2-(substituted
描述了含有 2-(取代苯基)quinolin-4(1H)-one 环的新型有机二硫化物的制备。该合成从用各种溴苯乙酮酯化的硫代邻氨基苯甲酸开始。在三氟乙酸中环化所得苯甲酰硫代邻氨基苯甲酸酯,得到 2-(取代苯基)-3-硫烷基喹啉-4(1H)-酮和 3,3'-二硫烷二基双 [2-(取代苯基)喹啉-4(1H) 的混合物-那些]。在邻二甲苯中加热混合物,得到高纯度的 3,3'-二硫烷二基双[2-(取代苯基)喹啉-4(1H)-酮]。二硫化物对包括多抗性亚克隆在内的各种癌细胞系表现出显着的体外细胞毒性。报告和讨论了获得的数据。(© Wiley-VCH Verlag GmbH & Co.
